MACHINE FOR RADIAL CRIMPING.

SPECIFICATION forming part of Letters Patent No. 284,749, dated September 11, 1883.

Application filed December 26, 1882 (No model.)

' and DAVID B. SMITH, of Troy, county of Ronsselaer, State of New York, have invented new and useful Improvements in Methods of and Machines for Radial Crimping, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

Our invention relates to that method of radial crimping in which radial or diverging or converging crimps, folds, or fold-marks suitable for filtering-paper are produced in filtering-paper or other material by compressing the paper or material on the lines of the several folds between suitable and suitably-arranged radial or diverging or converging grooves and edges. WVhen all the folds, foldmarks, or crimps required in a sheet of filter ing-paper are made by the simultaneous action of a sufficient number of suitable grooves and edges, the several edges pressing against opposite faces of the intervening paper cause friction and produce a strain, which is liable to tear the paper while it is being drawn in between the said grooves and edges by the simultaneous closing of the same grooves and edges upon the said intervening paper.

The object of our invention is to provide improved means for radially crimping filtering-paper or similar material, and adapted to form the radial crimps or fold-marks one after another or successively, instead of simultanegrooved bed-plate, and means for actuating said blades successively, or one after another, as hereinafter described.

In the accompanying drawings, Figure 1 is a side elevation, and Fig. 2 a plan, of a machine for radial crimping embodying our invention,and suitable for manufacturing radi ally crimped or folded filtering-paper. Fig. 3 is a side elevation, part section, of a slotted cam-rod, showing friction-roller in section, friction-roller stud, and a cam, showing also the relative position of the parts. Fig. 4 is a plan of fulcrum-shaft. Fig. 5 is a top view of 5 5 transverse guide-bar. Fig. 6 is a plan of camshaft with the several cams fixed thereon. Fig. 7 is an end view of the same, showing also a side elevation of one camrod in a position corresponding to the position of the shaft and 6c cams. Fig. 8 Ba diagram serving to facilitate the explanation of details.

In all the figures like parts are indicated by the same letters of reference.

A and B are suitable edge and groove carriers or holders, so arranged, guided, and operated that the several grooves and edges are opened and closed in the manner required for the purposes of our invention. The several carriers or holders B, grooves a, edges 1), cams d, rods O, rollers e, bearings 70, washers j, andstuds m are numbered as seen in the drawings, for convenience of reference.

All the grooves a and edges 1) which act on or receive one side of the paper are fixed to and carried by one and the same carrier, A. In the example shown in the drawings the carrier A is fixed, and is firmly supported by a suitable frame, F. The several grooves a and edges I) acting on the opposite face of the paper are carried by movable holders B, in the present example twelve in number. The several movable holders B are so operated that the same grooves a and edges 1) carried by them are caused to act one after another upon the paper in such manner that edge I) of carrier 13, for example, on the line of the first fold forces the paper into the opposite groove, to, of the carrier A, and holds it there until the next or adjacent holder, B has car- 0 ried edge Zr" into the opposite groove, a, &c., the several holders or carriers 13 acting in a similar manner successively until the last fold is made. The grooves a and edges 2), carried by holder or carrier A, all radiate from a 5 common center, 0, corresponding to the center of the sheet of filtering-paper to be folded or crimped. The grooves a and edges 12 carried by carriers or holders B correspond in form with those on carrier A, and when compressing the paper all radiate from the same point, p, separated from point only by the thickness of the intervening'paper. In the drawings the several carriers B are levers,

parallel for a part of their length with each other and with the central groove, a, and edge I), and are hinged to Aby a fulcrum bolt or shaft, I, and boxes J, boxes J being rigidly attach ed to lugs H, projecting from the said carrier A.

D is a hand-wheel secured to one extremity of a cam-shaft, G, which shaft is carried by bearing-boxes f, one of which boxes is shown in dotted lines in Fig. 1. Boxes f are supported by arms or brackets g, projecting from frame F.

The slotted cam-rods 0, connected severally at their upper extremities to the several carrier-levers B, are properly guided longitudi-.

nally by the holes or bearings k in the transverse guide-bar K, and are prevented from turning partially by the joint or connection with the carriers B and partially by the side faces of the several cams d. The middle part of the several cam rods- 0 is widened and slotted to span the hubs of the several cams d.

Twelve cams, d, differing from each other only in the length of the hub, are firmly secured to the camshaft G, and, acting severally on the several friction-rollers, e, communicate endlong motion to the several corresponding camrods, 0, to which the rollers e are attached. The friction rollers are held against the faces of the cams, and the return motion is secured by the action of spiral springs E, confined between washers j on the cam-rods and the under side of the transverse guide bar K. The transverse guide-bar K is securedto the frame by screws or screw-bolts passing through holes Zof the barK and into or through projections h of the frame.

Suitable studs, m, projecting from the faces of cam-rods G, carry the friction-rollers e. The hubs a of cams (1 pass through the slots of rods 0, allowingthe side faces of the cams to "approach the rods, as shown in Fig. 3.

c is an adjustable guide and gage consisting of a straight edge or face projecting .upward from the face of the carrier or holder A.

The center of guide 0 should coincide with the center 0. The gage and guide a is rendered adjustable by slots in the lugs g, by which it is secured t6 carrier A, for the purpose of so regulating the space 0 between the guide and the first groove that the first and last folds of the filtering-paper may be of equal width.

In the drawings the machine is represented in position to receive the paper or material 'to be operated on. The sheets of filtering-paper are to be first folded through the center on one diagonal, if the sheets are square, or on one diameter, if the sheets are circular. If the operator, placing himself in front of the machine at X, places one of the thus-folded sheets of filtering-paper upon carrier A, with the fold against the guide a, the center of the paper coinciding with center 0, and with the paper thus placed in position communicates motion with his right hand to the rim of wheel D in the direction of the arrow, the cam d, acting on roller 6, will force up the rod 0, and with it the short arm of the carrier-lever B, the long arm. of which lever carrying edge 1/ will force that edge'down on the paper and force the paper down into the corresponding groove, a, compressing it then and'forming the first crimp-fold or fold-mark required.

The form of cams d and their relative POSI- tions on shaft G are such that, the shaft G continuing to move in the same direction, the edge I) will reach its lowest position before If does, and will remain in that lowest position, holding the paper until bhas also reachedlts lowest position, forming the corresponding crimp, fold, or fold-mark; and so likewise of the succeeding folds, the carriers B B B,&c., coming down one after the other in the order of the numbers, each edge and groove holding the paper until the next succeeding fold or crimp is made. About two-thirds of one revolution of shaft G being sufficient to produce all the folds required, one complete revolution of shaft G completely crimps a sheet of filtering-paper and returns the several movlng parts of the machine to the position shown in the drawingsfiready to receive a second sheet 7 of' paper and repeat the operation.

Let Fig. 8 represent a possible section of the three carriers or holders B B B and a portion of the edge of carrier A. It will be seen thatthe grooves a a, and a are formed by bringing the several carrieis into the relatlve positions shown in the figure, B, for example, carrying the edge I) and one side each of grooves a and a; but, if preferred, for convenience or facility of construction, the several carriers B may be made. to carry any convenient parts or portions of the several grooves and edges.

It is evident that if the guide a should be removed from the fixed carrier A one half of a sheet of filtering-paper could be crimped by the machine without previously folding the paper through the middle or center, and that having thus folded, marked, or crimped one half, the other half could be foldedor crimped in the same manner. Therefore we do not confine ourselves to the crimping of sheets of filtering paper previously folded through the center; but,

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is p 1. In a machine for producing radial crimps or fold marks, a stationary bed plate or holder provided with grooves and edges radiating from a common center, in combination with a series of converging blades, and means,

substantially as described, for actuating said blades successively, or one after another.

2. In, a machine for producing radial crimping, a stationary bed-plate provided with holders pivoted all in the same axial line,

and operating substantially as described,

3. In a machine for producing radial crimps or fold-marks, a stationary bed-plate provided with grooves and edges radiating from a common center, in combination with a series of independently-actuated pivoted blades, also converging to a common center, and means, substantially as described, for connecting said blades with and actuating them from one and the same shaft, substantially as described.

4. In a machine for producing radial crimping, the fixed bed-plate or holder A, provided with the radial grooves a and edges 1), in combination with the parallel and independently-acting movable holders B, pivoted to the holder A, and provided with the converging blades or edges 7), and suitable rods connecting said holders with and adapting them to be operated all from one and the same cam-shaft, substantially as described.

In testimony whereof we have hereunto set 2 3 our hands this 14th day of December, A. D. 1882.
